Drilling accessories are tools and equipment that enhance the efficiency and effectiveness of drilling operations. Common accessories include drill bits, which are used to create holes in various materials, and drill chucks, which hold the bits securely in place. Other accessories may include extension rods, which allow for deeper drilling, and cooling systems to prevent overheating during operation. In addition to these, drilling rigs often utilize mud pumps to circulate drilling fluid, which helps to remove debris and cool the drill bit. Safety equipment, such as drill collars, is also essential to maintain stability and control during drilling activities.
